So the head broke off my alt tension bolt that tightens the serpentine belt,it is still hanging in there does anyone know the pitch and size? can I use a standard bolt from the hardware store?
To take it out I am gona wrench 2 nuts against each other to get a bite on it
without jacking up the threads.
Always something sheesh.......
Thanks gang very much!

I would guess that it's M8x1.25 but even if I'm right I don't know if you'll find a metric bolt that long at the hardware store.
The Subaru part number is 34435AA030. This happens often so a lot of dealers keep them in stock. It should only cost like $6 or so. If you buy it from a dealer make sure they're not giving you the A/C tensioner bolt -- that one is left-hand threaded.

Oh yeah, good point -- I believe all EJ engines use this same bolt, so a junkyard is a good bet.

Ok got the bolt from subaru, wron one they gave me LH thread.
So I went to home depot..nay. McfaddenDale had it for .80 cents.
The belt that is suppose to be oem is too big, maxed out the alt adjestment so I put a 34.5
inch belt and away i go.
